We report spectroscopic observations of PSN J22395067+3812443 in UGC 12137 discovered on UTC 2013 June 16.824 by Bin Wang and Xing Gao. A spectrum (range 330 - 1000 nm) was obtained on UTC Jun 27.27 UT with the Dual Imaging Spectrograph (DIS) on the 3.5-m ARC telescope at Apache Point Observatory. The spectrum shows prominent H-alpha emission with a P-Cygni profile. The minimum of H-alpha absorption is at 642.5 nm. Using the redshift z = 0.015627 of UGC12137 from NED, this corresponds to a velocity of 11000 km/s. Running SNID, the spectrum resembles SN2004et fifteen days after maximum. We classify this PSN as a Type II-P supernova.
